Red Hat Decision Manager provides a vast array of decision management functionality. From the Decision Tables feature in the new Decision Model and Notation (DMN) v1.1, which implements the full FEEL Compliance Level 3 of the DMN specification, to Predictive Model Markup Language (PMML).
Another powerful feature is the Complex Event Processing (CEP) engine. This engine provides the ability to detect, correlate, abstract, aggregate or compose and react to events. In other words, the technology provides techniques to infer complex events from simple events, react to the events of interest, and take actions. The main difference between CEP and normal rules execution is the notion of time. Where standard rules execution in Decision Manager deals with facts and reasoning over these facts, the CEP engine focusses on events. An event represents a significant change of state at a particular point in time or interval.
Recently, I was asked to demonstrate how Decision Manager CEP can be used in a real-time credit card fraud detection system. One of the requirements I was presented with ended up in an interesting rule implementation that forms the basis of this article. The requirement was defined as follows:

The all new and shiny Red Hat Decision Manager 7 has been recently released. Decision Manager 7 is the successor to Red Hat JBoss BRMS, our business rules and decision management platform. In this post we will have a look at the primary new features and provide instructions on how to get started with the new platform, either on your local machine or in an OpenShift Container Platform.
Red Hat Decision Manager 7 focuses on four main themes: Fit & Finish, Cloud-Native, Decision Model and Notation (DMN), and Business Optimizer.

Red Hat JBoss® BPM Suite and Red Hat Decision Manager (formerly Red Hat JBoss BRMS) both use an artifact packaging known as a “KJAR”, or knowledge artifact, since version 6. What is this file type? What separates it from a standard JAR file?
The basic summary
In very few words, a KJAR is a standard JAR file that has some extra files included. A KJAR keeps the same
.jar extension as a JAR file, because its basic file structure is identical to that of a JAR.

My name is Mario Fusco and I’m honored to be the Program Committee Lead of Voxxed Days Zurich for the third year in a row. Reading, evaluating, discussing, and selecting from the 200+ proposals that arrive every year is a long and challenging process. I must admit, I largely underestimated the task the first year I started doing it. It’s necessary to evaluate not only the quality of every submission, but also how they fit together. In the end, the worst part is having to reject so many incredible proposals because there are a limited number of slots.

The role of applications has changed dramatically. In the past, applications were running businesses, but primarily relegated to the background. They were critical, but more operational in the sense that they kept businesses running, more or less. Today, organizations can use applications as a competitive advantage. In fact, a well-developed, well-timed application can disrupt an entire industry. Just take a look at the hotel, taxi, and movie rental industries respectively.

There are many challenges related to building and architecting a web application, especially if you want to keep your codebase updated with modern techniques without throwing away a lot of your code every two years in favor of the latest trendy JS framework.
In our team, we can successfully keep a 7+ year-old Java application up-to-date, combining modern techniques with a legacy codebase of more than 1 million LOC, with an agile, sustainable, and evolutionary web approach.
More than just choosing and applying any web framework as the foundation of our web application, we based our web application architecture on 5 architectural pillars that proved crucial for our platform’s success. This post is a first in a series, that will discuss exactly that.
In the first week of October, Alex Porcelli and I had the opportunity to present at JavaOne San Francisco 2017, the two sessions we held related to our work: 5 Pillars of a Successful Java Web Application and The Hidden Secret of Java Open Source Projects.
It was great to share our cumulative experience over the years building the workbench and the web tooling for the Drools and jBPM platform and both sessions had great attendance (250+ people in the room).
In this series of posts, we’ll detail our “5 Pillars of a Successful Java Web Application”, trying to give you an overview of our research and a taste of participating in a great event like Java One. Let’s talk about them:
